Abstract (en)

[origin: WO2012059268A1] The invention relates to a fuel injection system, in particular to a common rail injection system, comprising a pre-supply pump (1) and a high-pressure pump (2), wherein the high-pressure pump (2) is used to apply a high pressure to the fuel and comprises at least one pump element having a first valve, which is used as inlet valve (3), and a second valve, which is used as an outlet valve (4). According to the invention, the pre-supply pump (1) is an electrical fuel pump, by means of which a pre-supply pressure can be achieved, which is equal to or greater than the total opening pressure of both valves (3, 4) of the pump element such that rapid filling and/or venting can be effected during the initial start in the vehicle plant or when restarting after an empty tank. The invention further relates to a method for filling and/or venting such a fuel injection system.
